I'm with you on finding this personally annoying. But the question is whether a dedicated forum for discussing suicide or rape, one where the incentives of an unqualified influencer paid by views and product endorsements are better considered, is superior for these matters.

We don't, by analogy, randomly launch into suicide and rape in the middle of a cocktail party. Instead, we naturally seclude ourselves with the people we want to discuss it with, people we tend to have chosen thoughtfully, and usually with some warning that what we want to discuss is weighty. Not doing any of that online strikes me as, if not a problem, a legitimate concern.
